When I heard a grinding sound from the rear of my 2005 Envoy, it reminded me that I hadn't checked the rear brakes in too long. Once I pulled the rear wheels off, I found that the rear pads had gotten so low that they wore deep grooves into the rotors. Replacing the pads and rotors on the rear of my Envoy was not much different than any other standard brake job.
I lifted the rear by the center contact point on the rear differential housing, and put jack stands under the rear axle on both sides of the differential housing. After removing the caliper and pads, I removed the bolts securing the caliper bracket, and pull the bracket from the rear hub. My GMC Envoy still had the rotor-retaining rings on the wheels studs, so I pulled those off first, then pulled the rotor off.
When I installed the caliper bracket, I tighten the bolts to 148 foot-pounds of torque. After lowering the caliper onto its bracket, I applied disc brake grease to the smooth part of each caliper bolt, then installed the bolts and tightened them to 23 foot-pounds. I tightened the lug nuts to 103 foot-pounds.
